IMPROVEMENT m FASTENINGS FOR ,sEAjrs FoR. WAGONS ORbSLEI GHS.

The Schedule referred to in these Letters f atent and making part of thesame.

Be it known that we, Jomv G. KNAPP and JOHN F. Bonnnrsomof Warwickflnthe county of Orange and in the State of New York, have invented certainnewand useful Improvements in Fastenings for Oarriage or Sleigh-Seats;and do hereby declare that the thllowi'ng is a full, clear, and exactdescription thereof, 3 reference being had to the accompanying drawingmaking'a part 'of this specification, in which- .Figure l is anelevation of the end of a seat and. i pf the side rail of the body asattached together;

Figurel2 is a likeviewof said side rail with the iseatreinoved andFigure 3 is a vertical cross-section on the line a; x

, Letters of like name and kind refer tolike parts in 1 each of thefigures. v y e The object of. our invention is to provide a, fasten "ngfor the'back or adjustable seat of a carriage or sleigh, that shall-beefficient and durable, while at the ame time simple in constrhctionandcomparatively incxpensive; and v e p g a It consists iu the employmentof a dovetail bar, secnredto or upon the inner faceof the body-side, andengaging with a lugyprovided with a suitable corresponding groove, andsecured toj-thei-nner face of the end of the seat, and. in combinationtherewith ot a pring placed within a groove in the face of said dovetailbar, soas to engage with and lock thereon said lug, substanti llyasis-hereinatter shown and described.

. .In the annexed drawing A represents the side of'the body, secured vto-the inner face of which,near. its, upper edge, is a -1-'a.il,;B,

i'orthe support of the seat O.

Attached to or upon the inner face-of the railB is a metal bar,1D,having paralleledg'es, which, as shown in fig. 3, are beveled inwardfromtthe inner face to the outer face of. said bar, was to give to thesame a dovetail form, transversely.

i .A metal Jug, E, provided upon its outer face with a groovecorresponding in size and shape to the bar YD, is secnredupon andprojects downward from the end piece 0" of the seat, so that, when thelatter is in line with the draft,- a shoulder, d, is provided upon thelower edge of the bar D, at or near its rear end, and,

engaging with the lug E,.prev'ents thesame from passing further to therear, while forward motion is.

prevented" by means of a spring, F, provided with a hooked end, f,-andsecured within a groove cut in the inner'faee of said bar D, so thatsaid hooked end shall engage with the front end of said lug;

To place the seat in position it is only hec'essaryto rest it upon therail B, infront of the bars 1), and

then slide it to the rear, by which means the-front V end of the springs(which are beveledinward and rearward) are pressed within their groovesby the lugs, so as to permit the latter to pass over. said barsuntilthey reach the shoulders d,when said springs willbe released, and,pressing outward, lock-said lugs in place. e

To remove the seat 'the springs are pressed outward until the lugs arereleased, when said seat may be drawn forward. I 1

The especial advantages, possessed by this device are that it affordsperfect security of position to the seat, is durable, simple inconstruction, and can be furnished at acoiuparatively Sillitll cost. 3 l

Having thus fully set forth the natnreanrl merits of our invention,

What we claim as new. is-

The bar D, provided-With the shoulder d, the lug I], and the spring F,whenconstructed as described, and combined with the seat 0 and rail B,in the |nanner and for the purpose substantially as specified.

In testimony that we claim the foregoing we have hereunto set our handsthis 11th day oi January,

, JOHN G. KNAPP.
